tcp/ip fake endpoint for machine vision example

[emakeiv]

This example assumes that user has a working machine vision camera that provides
data on specific template:
[Start, Pattern_1, X_1, Y_1, Theta_1, Match_percentage_1, Pattern_2, X_2, Y_2, Theta_2, ‘Match_percentage_2, Pattern_3, X_3, Y_3, Theta_3, Match_percentage_3, end]
it would be really great if example also provided a fake tcp/ip server endpoint in case user doesn't have smart camera (Datalogic T47 etc.) or CV software to get real data that complies with read_tcp_ip method.
It might be used as a starting point for developing custom CV solution
